Abstract: A construction apparatus having an arrangement for controlling guidance of a frame thereof along a predetermined path, e.g., a slip-form paving apparatus, has an arrangement for selectively digging vertical bores in the ground surface at spacings along the predetermined path for planting of vertical posts to be secured by the paving material upon setting thereof. In operation, as the construction apparatus is guided over the ground surface along the predetermined path, the bore-digging arrangement is periodically actuated to form vertical bores at spacings along the predetermined path, after which a settable paving material is formed along the predetermined path including filling the vertical bores with the paving material, and posts are placed vertically in the holes for securement therein.
